The seven 14th century rectangular reliefs depicting episodes of the lives of saints Ottaviano and Vittore are particularly noteworthy. Four of the panels relate the story of the procession and martyrdom of Saint Vittore while the other three relate the story of Saint Ottaviano. Venturi has attributed the seven panels to Agostino di Giovanni and Agnolo di Ventura.
